The CA F403 clamp meter user manual provides safety instructions, operation steps, technical specifications, and maintenance guidance.
This manual introduces the CA F403 clamp meter, describing its functions such as current, voltage, resistance, frequency, temperature, and True‑Inrush measurements. It explains the device’s safety classifications (IEC‑61010‑1/‑2‑032, CAT IV 1000 V) and outlines proper usage, configuration, and measurement procedures.
The document also details technical parameters, environmental limits, battery replacement, cleaning, calibration (at least once per year), and warranty information. A list of accessories included in the package is provided at the end. This manual is written in Chinese.
